In the query option, maxFetch settings are not applied to the emitAll case

[jhorbulyk]

In #133 a maxFetch value was added to many lookup actions. However, it was not applied to all code paths. For instance, int the query.emitAll case, this change has not been applied: https://github.com/elasticio/salesforce-component/blob/master/lib/actions/query.js#L96-L123
